Solvent oil can be divided into three categories: low boiling point solvent oil, such as 6 # solvent extraction oil, boiling range of 60-90 ℃;
In the boiling point solvent oil, solvent oil, such as rubber boiling range is 80-120 ℃;
High boiling solvent oil, solvent oil, such as paint boiling range is 140-200 ℃, has been widely used in recent years in the printing ink solvent oil, dry point can be as high as 300 ℃.
In general, 60 ~ 90 ℃ as extraction solvent oil, namely it is often said that 6 # solvent oil;
80 ~ 120 ℃ is called rubber solvent oil, that is, it is often said that the 120 # solvent oil;
140 ~ 200 ℃, called paint solvent oil, 200 # solvent oil.
In addition, there is ink solvent oil, dry cleaning solvent oil and so on.
Sometimes, the cutting of the distillate will be different.
6 # solvent oil, for example, some manufacturer scope of distillation range is 60 ~ 75 ℃, usually we call it a narrow 6 # solvent oil, to show the difference.
According to the actual production, 120 # solvent oil distillation range tended to be controlled between 90 ~ 120 ℃
